Decoding Calldata

This repository contains a script to decode calldata for a sendQuote() using SYMMIO's contracts, specifically designed to extract and display the input parameters from a transaction's calldata.

Dependencies

web3.js: A JavaScript library to interact with the Ethereum blockchain.

Installation

To use this script, you need to install web3.js. You can install it using npm:

npm install web3

Script Overview

The script decodes the calldata of a transaction to reveal the input parameters of a sendQuote() call. In this example, it decodes the _call function's calldata, and further decodes the sendQuote function's data within _callDatas.

How It Works

Initialize Web3: Creates a new instance of Web3.

Define ABI: Specifies the ABIs for both the _call and sendQuote functions.

Decode Main Calldata: Decodes the primary calldata to extract the _callDatas array.

Decode Nested Calldata: Decodes each element in the _callDatas array using the sendQuote ABI.

Filter Named Outputs: Extracts and prints only the named properties from the decoded data.

Usage

1. Clone the Repository

2. Install Dependencies: Ensure web3.js is installed.

3. Replace Calldata: Replace 'YOUR_CALLDATA_HERE' with the actual calldata in the script.

4. Run the Script: Execute the script using Node.js.
